Unconventional Machining

From the point of view of the concept itself, technology is a set of processes, rules and habits used in the production of various objects in the most diverse spheres of production, or human activity itself. Therefore, there are several designations and naming of production technologies in the professional literature. Historically, probably the oldest systematic designation and division of production technologies and processes is given as early as 1963 in the German standard: Begriffe der Fertigungsverfahren DIN 8580. The standard defines production processes for the production of geometrically certain solids. In the paper is shown explanations of mechanisms of machining when is used unconventional machining technologies.

AbstractToday’s industry relies not only on raw material processing, but also on information. The huge amount of data obtained during the production process of goods and services; as well as information about the context of the production processes has made it necessary to account for, methodize, analyze and react in order to achieve a competitive market share. Fortunately, this technological leap has been able to support the above process, but the presence of those new technologies requires adequate preparation from the point of view of human resources too.

Processing Mechanisms

Abstract Most cognitive psychophysiological studies assume (1) that there is a chain of (partially overlapping) cognitive processes (processing stages, mechanisms, operators) leading from stimulus to response, and (2) that components of event-related brain potentials (ERPs) may be regarded as manifestations of these processing stages. What is usually discussed is which particular processing mechanisms are related to some particular component, but not whether such a relationship exists at all. Alternatively, from the point of view of noncognitive (e. g., “naturalistic”) theories of perception ERP components might be conceived of as correlates of extraction of the information from the experimental environment. In a series of experiments, the author attempted to separate these two accounts, i. e., internal variables like mental operations or cognitive parameters versus external variables like information content of stimulation. Whenever this separation could be performed, the latter factor proved to significantly affect ERP amplitudes, whereas the former did not. These data indicate that ERPs cannot be unequivocally linked to processing mechanisms postulated by cognitive models of perception. Therefore, they cannot be regarded as support for these models.

Over Time

By sharing their world, humans and other animals sustain each other. Their world gets determined over time as generations of animals act in it. Current approaches to psychological science, by contrast, start from the assumption that the world is already determined before an animal’s activity. These approaches seem more concerned with uncertainty about the world than with the practical indeterminacies of the world humans and nonhuman animals experience. As human activity is making life increasingly hard for other animals, this preoccupation becomes difficult to accept. This article introduces an ecological approach to psychology to develop a view that centralizes the indeterminacies of a shared world. Specifically, it develops an open-ended notion of “affordances,” the possibilities for action offered by the environment. Affordances are processes in which (a) the material world invites individual animals to participate, while (b) participation concurrently continues the material world in a particular way. From this point of view, species codetermine the world together. Several empirical and methodological implications of this view on affordances are explored. The article ends with an explanation of how an ecological perspective brings responsibility for the shared world to the heart of psychological science.

Vector-borne transmitted helminthic zoonosis affects the health and economy of both developing and developed countries. The concept of episystem includes the set of biological, environmental, and epidemiological elements of these diseases in defined geographic and temporal scales. Dirofilariasis caused by different species of the genusDirofilariais a disease affecting domestic and wild canines and felines and man, transmitted by different species of culicid mosquitoes. This complexity is increased becauseDirofilariaspecies harbor intracellular symbiontWolbachiabacteriae, which play a key role in the embryogenesis and development of dirofilariae and in the inflammatory pathology of the disease. In addition, the vector transmission makes the dirofilariasis susceptible to the influence of the climate and its variations. The present review addresses the analysis of dirofilariasis from the point of view of the episystem, analyzing the complex network of interactions established between biological components, climate, and factors related to human activity, as well as the different problems they pose. The progress of knowledge on human and animal dirofilariasis is largely due to the multidisciplinary approach. Nevertheless, different aspects of the disease need to continue being investigated and cooperation between countries and specialists involved should be intensified.

Pedagogical Learning

In order to understand and describe the internationalization behavior of companies, the first research carried out before the 1970s focused on large multinationals whose internationalization strategies were made possible by heavy investments. Other research on the internationalization of SMEs, conducted in the United States and Europe in the early 1980s, has given rise to behavioral models in stages where size is a barrier to internationalization. However, we find that very small businesses (TPE), newly created, inexperienced and with limited resources, internationalize and thwart the classic models of internationalization by scrambling the stages. Age, size and resources are no longer barriers to internationalization. This makes Cavusgil (1980) say that the gradual internationalization of companies has become obsolete. Veilleux and Ferro (2010) confirm that today, between 1 and 2% of new businesses are international when they are created and 76% have export prospects in the first two years. And the majority of research carried out since the 1990s deals with the precocity and rapidity of this internationalization from a point of view external to the company such as the saturation of local and / or national markets, the liberalization of international markets or the aid provided by governments, competitive pressure; and from an internal factors point of view such as the role of the manager and his various experiences, the support of his social networks, the use of new communication and production technologies, the characteristics of the product. However, there are very few works that address the internationalization of these VSEs through pedagogical learning in international entrepreneurship; learning mediated by the University, quickly enabling these companies to position themselves on an international market. The object of this research is precisely the questioning of the relevance of this learning; and this, through our participation in the training "International Entrepreneurship and Development of the Global Enterprise" initiated by the "College of Business" of the University of Indiana (ISU). It is a training program, offered by the ISU "College of Business", bringing together Universities from four other continents: Europe, America, Asia, Africa & l 'Oceania. A mixed group of teacher-researchers and researchers from these different universities benefited from this training program.

From May 2006 to December 2006 an odour exposure study using field panel observations according to German standard EN3940 was carried out around an installation for reception and sorting of urban solid waste and treatment of the organic fraction using anaerobic digestion and composting, with a capacity of 240.000 tonnes of waste annually. The exposure study covered an area of 2000 × 4000 meters, including the residential area of Ripollet, the Can Salvatella industrial estate and a rural area with various animal production facilities. The results were compared with the German criteria for residential and industrial areas of 10% and 15% odour hours respectively. These criteria were exceeded in the vicinity of the installation, including part of the industrial area of Can Salvatella, but not exceeded in the residential area of Ripollet. The odour impact was also modelled using dispersion modelling. Two models were applied, ISCST as an example of the more traditional Gaussian plume model and CALPUFF in 3 dimensional mode as an example of more advanced modelling. The meteorology in the area is challenging, from the modelling point of view, with frequent calms and low wind velocities, combined with a pronounced day/night circulation pattern. The results of the three methods of odour impact assessment are applied and the model results are compared and validated against the observed odour frequencies over the six month period of the study. The Gaussian ISCST model proved to be unable to effectively predict the odour footprint as determined by direct field observations of exposure, overestimating the distance of impact substantially in the direction of prevailing winds. The CALPUFF model in 3D mode did predict the area of measurable odour hour frequencies quite well. The 98 percentile for 3 ouE·m-3 appears to be a bit more restrictive than the German <10% odour hours criterion applied in German regulation.

Innovation Activities

The paper deals with an actual issue focused on one of the world wide problem – effective development of an innovation process in the company. Just innovation is deemed as an essential part of company’s efficiency and its development with an impact on overall performance and competitiveness. The purpose of this paper is to present and discuss knowledge and findings of original primary research into South-Moravian companies within two projects of Internal Grant Agency Faculty of Business and Management Brno University of Technology, which were conducted in 2009 and 2010. For this analysis a questionnaire survey was used – the results of the primary research reflect innovative activities from the top managers’ point of view. The scientific aim of the paper is to gain knowledge and analyse the present status of innovative activities as it pertains to Czech and foreign professional literature and in the Czech business environment. Authors proved with help of questionnaire survey that many companies still neglect information support of their innovation activities although given the importance of innovation as an engine of growth. Moreover, as shown by the primary research, the majority of companies lack a sophisticated marketing information system, modelling and analysis of the future market, analyses of customers, their behaviour and unsaid needs, definition of price strategies, and analysis of new expansion areas. These findings are not affirmative for our business environment.

The goals of human activity are diverse, ambiguous and often opposite. In the article, goal-setting is seen in the context of the concepts of freedom and necessity, as a subject-object attitude, from the point of view of a dual role of consciousness – as knowledge (usually incomplete, personal, sometimes distorted) about the object to which the action of the subject is directed, and as an attitude to the object. The goal-setting is determined by the needs of the person, his interests in material life and other spheres. The dominance of the market order and private interests in an individualized society gives social development a spontaneous character – a development driven by many different goals, but not by common purpose. In the process of social development a discord is arising between private interests and social needs. Hence there is the need for development guided by social foresight in order to prevent threatening tendencies. In the light of global challenges and threats, the optimal combining of private and common human interests is becoming an increasingly urgent task, requiring changes in traditional priorities. The Sustainable Development Goals approved by the UN summits should be considered in terms of creating conditions for the survival of mankind.

The article deals with the dependence of the competitiveness of industrial enterprises on the level of innovation activity. The essence and main characteristics of the competitive advantages of the enterprise from the point of view of innovative activity in the course of innovative activity are highlighted. One of the factors that can increase the competitiveness of business is the active use of innovative production technologies, which will ensure a continuous improvement of scientific, technical, industrial, financial and social activities in the context of changes in the institutional environment. The results of analytical research of priority sectors of Ukrainian economy from the point of view of innovative activity are presented. With the transition of the economy to the next technological institution, it is worth talking about the change of priority industries in the structure of industry - from low-processing with low added value to innovative high-tech and high-margin. As the first Ukrainian Business Innovation Index showed, only some companies are ready to invest in innovation and have a strategic vision. According to research, most companies are still not ready and do not plan to make fundamental changes in their business models in the near future. Innovation is limited to the introduction of new production technologies, automation of tasks, training of staff new skills, changing approach to marketing and communications. The necessity of systematic support of innovative activity is substantiated, the basic directions of optimization of structure of economy of Ukraine are allocated. The European vector of Ukraine gives a good chance to digitize the processes. In particular, for state-owned companies in areas such as energy and oil and gas, the prospect of digitalization has become the prospect of entering the European Union. However, without major changes to the regulatory system, government priorities, and extensive government-business cooperation, no real major changes can be expected. The issue is not only in the tax field or subsidization, but also in education, digital skills of the population. The necessity of updating the issue of development of high-tech sectors of the economy has been proved, which will increase the competitiveness of industrial enterprises. Given the trends identified, it is appropriate to emphasize the need to take concrete actions to change the structure of the economy, to increase exports of high-tech products, the creation of export-credit agencies, industrial parks.
